No - After all the disputes our MB Dealer first fitted All Season Tyres Free of charge. Then MB HQ developed the Knuckle replacements and these were also fitted Free of charge.

Hope this helps

My brother in law got his money back last week into his account - £19000. He had a GLC 43 which as part of the ombudsman agreement has been returned.

Please read the decision as follows direct from the ombudsman

https://www.financial-ombudsman.org.uk/files/259069/DRN1169848.pdf
After having my case, for exactly the same issue, decided in favour of Mercedes UK I just don't understand how the Ombudsman works. Surely we should all be treated the same? The Ombudsman ruled in favour of Mercedes because Mercedes admitted this was a 'characteristic' (I hate that word now) of the car. When I sent them the PDF of the decision that was ruled in the customers favour, for exactly the same issue, they said that there were different rules for cars purchased via 'hire purchase' as to those that were via 'lease'. I've no idea if this is correct as I know nothing about this sort of thing...so I've just had to accept it. As this characteristic must have been there at the point of sale the Ombudsman said to open a new case with them against the dealership that sold me the car. Their point being it would not have been of acceptable quality or 'fit for purpose' at the point of sale thus violating the 'sales code'.

Overall gutted that the experience of owning such a car has been blighted by this problem. The intention was to purchase the car outright next June at 36 months of ownership but there is no way we will do that now - we will have to return it losing over £30k in 3 years.

I can't see us getting anywhere with the second Ombudsman case but will update the forum accordingly when I know more.

Disgraceful - shocking to hear the Ombudsman has double standards.

Owners of Left-hand drive GLC’s and other MB’s probably won’t understand what all this fuss is about. But it really does Drive you CRAZY - such an awful juddering & clonking & wheel skipping

Great car overall, but the Crabbing Fault is just SAD

Ours is a 250D AMG Line on 20” wheels. After 12k miles the original front tyres were completely worn on the outer 2 inches. Complained but dealer said it was normal for a heavy car - bs.

MB UK then fitted All Season tyres FOC. Claiming this would stop the crabbing, it didn’t, but was slight improvement while on new rubber - flex in new tyre absorbed and masked the Crabbing.

After 3 years MB HQ came up with the New Knuckle Fix, FOC Another improvement and makes the car acceptable, but not 100% fixed

To answer your question - the replacement All Season RF tyres have now done 20k miles and still looking good with even wear. So the New Knuckle Wheel Alignment has made a big improvement to Crabbing and tyre wear.

Definitely have the fix done if you are planning to keep the car for a few years. It will pay for itself just in tyre costs.

Make sure the dealer does a Full Wheel Alignment check after fitting the new knuckles - essential!

Hope this helps

Tyre wear is another issue resulting from the crabbing 'characteristic' (problem) - on 3rd set of tyres and we've done 13k miles!!

Hi Tony.
I am new to forum but very interested in your case.
I have a GLC220D purchased new March 2018. Currently the car has done 13600 miles but the front 2 tyres have abnormal wear. Please see photos attached. The wear is identical on both tyres and nearly all the way around the outer edge. Would this be the same type of issue you had which was resolved and if so, was the knuckle fix before or after March 2018?
Thanks

Hi Mellie,

Yikes - your tyres are awful. Looks like the Crabbing is pinching and pulling chunks of rubber off the tyres.

The outer edges of our tyres were essentially worn smooth, but did also show signs that the crabbing was pulling rubber off the tread pattern - not as bad as yours, which looks dangerous.

Initially our dealer said the excessive wear was normal, until MB HQ admitted to the fault and fitted the new knuckle joints. Tyre wear is now consistent across the width of tread and also much reduced wear - in line with all other cars we’ve owned.

I would recommend calling MB UK and arrange to email them your photos - that is not normal wear for a 2L Diesel

Good luck at the dealers

Tony

Thank you Tony for your details. I would agree the tyres are dangerous. I have a complaint logged with Mercedes-Benz UK and will chase dealer tomorrow. Will let you know the progress. Thanks again.

Dealer Service Manager said are changing front tyres to All Weather as a gesture of goodwill😃
The problem he said comes from turning full lock as an example getting into and out of driveway. I will speak to Mercedes HQ to confirm the car has the latest steering fix applied which service manager said has. The fronts are not run flats as he didn't have them. I need to find out if manufacturing fault then as Service manager said it was because car is heavy!
Apparently car has latest steering knuckles on which I will raise with Merc HQ to confirm too!

Our dealer originally said it was normal for such a heavy car - rubbish. Also, when turning into a driveway or sharp corner the car should just roll around, and not be ripping chunks off the tyres.

Important - after the Knuckle fix they should have done a Full wheel laser alignment.

if your car has the fix, I would say the alignment is out

Our car is running on Run Flat All Season tyres

Thanks Tony.
Will send email to Merc HQ and see what they say re the knuckle upgrade and full lock excuse for the tyre issues.
Update to follow soon.
Cheers

I have a 19 plate GLC43 with the same problem. I have the same clucking/skipping problem and tyre wear in the same outside area being caused by the diff not allowing the wheels to rotate at different speeds when turning. I reported this to my local dealer in October last year, to be told firstly it's a normal characteristic of the car. After some research I found this thread and went back to them and requested to speak to the manager and they conceded there is a problem which gets worse in winter when the weather becomes colder and the compound of the tyre becomes harder and less grippy which forces the diff even less. They said the only option is to fit winter tyres and implied at my cost. After some pushing to investigate replacing under warranty they informed me MB UK do offer winter tyres as a warrant replacement but you must apply for them through the dealer that originally supplied your vehicle because MB UK may only cover a percentage of the cost and if you go through your original dealer they will have to cover the rest under "fit for purpose" regs. It took a few months but MB UK supplied me free of charge a set of winter tyres on 19" 5 spoke alloys. They supplied them on a new set of rims as the only MB certified winter tyres available are the same width as the front wheels on the GLC43 not the wider rear wheels. For me it 100% cured the problem, not skipping or juddering, but I hated the look of them and only used them for a couple of weeks up to and including a skiing trip and then put the original bi colour ones back on (forgot how good it looked until I had them back on!). Once the standard front tyres have worn out on the front wheels I am now considering just putting winter tyres on the front wheels and seeing how that goes. It was nice to get £3k worth of tyres and wheel for nothing but I would rather it just worked! Also you need to be able to store a second set of wheels.

Hope that helps anybody at the start of the problem not knowing what to do!

This may have changed but my dealer originally told me that MB do not certify a winter tyre for the 21" wheels.

Hi Tony.
Update from Customer Serviceat MB following a email sent to Mr Savage CEO MB
They responded on his behalf and quoted
"
this matter has been investigated with the Mercedes-Benz of Hertford and the Retailer have confirmed that there is no manufacturing defects on the car that would of caused the tyres to wear. However the Retailer have given a set of all season tyres as a goodwill gesture due to the dissatisfaction.

As there are no manufacturing defects on the car and tyres are a wear and tear item we are unable to investigate this matter further."
So basically there is no underlying reason why the tyres were in that state other than normal wear and tear.

What a load of old rubbish.

Little more I can do other than get the motoring ombudsman to investigate

I don't want to pay for replacement tyres if this happens again.

Maybe I won't park on a driveway as the idiots think that's the reason.

Cheers

Shocking response :(

You will be wasting your time going to the ombudsman - they have been useless for most owners, although some have had a positive decision. But these cases are when the cars are financed - why that makes any difference is crazy.

You could try a tyre specialist - my local tyre supplier was shocked at the specific wear rate on ours and was prepared to back my position. Your tyres look even worse.

I personally could not live with having to swap to winter tyres.

The really annoying thing is, there are thousands of GLC owners living with this fault, who have said nothing. Because it’s an MB they believe it couldn’t possibly be a design fault - IT IS AND SHOULD BE FIXED BY MB

Good luck
Tony

I just wanted to add to this thread, as I read it last year and learnt a lot.

Bought GLC May 2019 - 220d 2016.

Didn't notice any juddering for a while, I though we were safe. Winter and wet weather kicked in, October 19 onwards, really bad on full lock, we have 19" alloys which apparently makes it worse.

Spoke to my local Mercedes garage (after a checkup), workshop guy basically said, it is common with cars of this size, with the torque etc, basically trying to fob me off. I've thankfully owned a lot of cars, all shapes and sizes, disagreed with him throughout 😂

Left the garage went home, did some more reading on here, saw a statement on this thread from the same garage, got angry and called Mercedes HQ (main number on global site). Logged the issue, they said a local garage would come back to me, 2 days later get a call to book the car in, I book it in. Closer to the booking date, I get an email saying this issue is most likely going to cost, BUT they then go on to say they have a solution and what it is (mechanical fix not tyres) but it would cost something like £1100.

Thankfully that p155ed me off enough for me to quote their email back and highlight how they acknowledged a fix was possible, and a fix clearly states a fault etc. This went on for a while, then I said i'd go back to Mercedes HQ and start questioning known faults and how this could be dangerous - unnormal tyre wear etc,

Email back, saying car booked in, cost covered and would I like a loan car.

So a big thank you to everyone on here sharing their information, without it, i'd of conceded at round 1.

FYI - problem solved 100% and to be fair, the garage were brilliant after they agreed to fix the issue, I will always return for a service and will buy future cars from them.
